Calculate the hydrogen ion concentration of a 2.30×10^-1 M solution of the strong base RbOH. Round your answer to 3 significant digits.

would the answer just be 2.30E-1 because the hydrogen ion will dissociate completely?? help appreciated thanks

Yes, you are correct.

To calculate the hydrogen ion concentration of a solution, you need to know if it is an acidic, basic, or neutral solution. In this case, we have a solution of the strong base RbOH.

When a strong base dissolves in water, it dissociates completely, meaning it breaks apart into its ions. In the case of RbOH, it dissociates into rubidium ions (Rb+) and hydroxide ions (OH-). Therefore, there are no hydrogen ions (H+) present in the solution.

So, the hydrogen ion concentration in this case would be zero. The answer would not be 2.30E-1 because there are no hydrogen ions to begin with.

Keep in mind that a strong base such as RbOH actually contributes hydroxide ions to the solution, which makes it more basic rather than acidic. In this case, the concentration of hydroxide ions would be 2.30×10^-1 M.
